Topic: Nexus one & multi touch (Read 2452 times)

i've spent several hours to implement a multi touch based control system. basicly one joystick like touch button on one side of screen and one jump button on other side. i've tried several different ways. none were as good as i expected. movement goes jerky at some point. finally i tried 4 separate arrow buttons and a jump button. didnt help either.

it basicly says, N1's screen is not capable of multi touch. when two touch points come too closer or their axes come closer, hardware cannot separate two signals. their coordinates flip. as this is a hardware issue, there is no workaround. many HTC phones have the same issue since they use the same screen.

That's why i added trackball controls to my game in addition to touch events. Not all devices have one (mine has some keys for it, which is virtually the same things), but those who have will benefit from that.

that doesnt stress N1 that much. framerate hardly drops %10 or so when screen is touched. but i suppose as written there, this mostly effects older phones.

multi touch in software came with android 2.0. as i read, most older samsung phones (like your galaxy) has a resistive screen. so even if you update it to 2.0 it wont support multi touch. as it has a capacitive screen, G1 does support it, if you even call it a support

No, i just posted the benchmark result of one. As much as i like the Galaxy S, because it wipes the floor even with the N1, i dislike Samsungs update policy. So i'm not sure, that i would buy a Samsung again...
